How a global fashion retailer found $1M in savings — six stores at a time.
A retailer with 400+ stores across 50 countries. A sustainability pledge to back up. No visibility into which stores were actually wasting energy — until a six-site pilot proved the model.

The Problem
With hundreds of stores across dozens of countries, the retailer had no way to see where energy was actually being wasted — store by store, in real time.
The Approach
Renteknik piloted store-level monitoring across six sites, feeding live energy data into the retailer’s own building management system so facility and energy managers could see consumption at every location, not just on a utility bill months later.
The Results
A 15% cut in energy use at the pilot sites, with enough proven value that the rollout is now extending to 60 stores across three continents — a projected $1M in annual savings once fully deployed.

01
One Pilot. A Global Rollout.
Six stores proved the model. Sixty stores are scaling it.
- Piloted at 6 sites before any wider commitment
- Data fed directly into the retailer’s own building management system — no new dashboard for store teams to learn
- Now expanding across North America, Europe and Asia
- Model designed to repeat at every store, not just the pilot sites
Six stores answered the question. Now the question is how fast the other fifty-four can catch up.
Not a pilot. A blueprint.
